Coastal communities are particularly vulnerable to the impacts of climate change, including sea-level rise, increased storm intensity, and coastal erosion. This comparative analysis examines adaptation strategies implemented by coastal communities around the world to mitigate these risks and build resilience. Drawing on case studies from diverse geographical regions, the study evaluates the effectiveness of various adaptation measures, such as coastal defense infrastructure, ecosystem-based approaches, and community engagement initiatives. Through a synthesis of best practices and lessons learned, the paper offers insights for policymakers, urban planners, and practitioners seeking to develop sustainable adaptation strategies in coastal areas.
